Amprobe MEGATEST-5000 Megohmmeter - Manual (Page 4)

1. Accident prevention and safety measures
Please read and understand these instructions BEFORE using the AMB-5KV-D.
This instrument can generate dangerously high voltages.
Only specialised personnel, well trained about electricity and its effects must use it.
When testing, the following is important:
• DO NOT TAKE MEASUREMENTS IN AN EXPLOSIVE ATMOSPHERE. i.e. GAS,
FUELS OR DUST.
• Do not take measurements in wet environments
• Do not touch exposed metal parts; i.e. alligator clips, ends of test leads, circuits, etc.,
while taking measurements
•
Prevent any accidental contact of yourself or others with the measuring voltage.
• Make sure the test voltage does not damage any component unable to withstand it.
The following symbols have been used in this manual:
o
Warning: comply with the instructions in the manual. Any improper use could
damage the instrument, the equipment being tested or cause personnel
injury.
p
Danger High Voltage.
t
Instrument with double insulation.
1.1 During use
Following are two general guidelines for setting up the tests. These must be integrated
from time to time with a detailed analysis depending on the actual circumstances.
While measuring on equipment:
- Seal off the testing area and do not allow other people to approach it. If
necessary, put up a sign.
- Have enough room available, plus properly insulated tables or supports.
- Take note of which parts could be live should there be defective insulation.
- Keep the area and the measuring cables clean from dust, oil or other foreign
matter.
- On a routine basis, check for any abrasion or breakage on the measuring
cables.
- Never exceed the maximum testing voltage for which the tested device was built
and/or rated.
